在冷端采取一定措施補償由于冷端溫度變化造成的影響稱為熱電偶的冷端補償正常。與測量儀表連接用**補償導線。是一種感溫元件，是一種一次儀表，熱電偶直接丈量溫度。由2種不同成分材質(zhì)的導體組成的閉合回路，由于材質(zhì)不同，不同的電子密度產(chǎn)生電子擴散，穩(wěn)定均衡后就產(chǎn)生了電勢。當兩端存在梯度溫度時，回路中就會有電流產(chǎn)生，產(chǎn)生熱電動勢，溫度差越大，電流就會越大。測得熱電動勢之后即可曉得溫度值。熱電偶實際上是一種能量轉(zhuǎn)換器，可將熱能轉(zhuǎn)換成電能。熱電偶的技術(shù)優(yōu)勢：熱電偶測溫范圍寬，性能比擬穩(wěn)定；丈量精度高，熱電偶與被測對象直接接觸，不受中間介質(zhì)的影響；熱響應(yīng)時間快，熱電偶對溫度變化反響靈活；丈量范圍大，熱電偶從-40~+1600℃均可連續(xù)測溫；熱電偶性能牢靠，機械強度好。運用壽命長，裝置便當。電偶必需是由兩種性質(zhì)不同但契合一定要求的導體（或半導體）材料構(gòu)成回路。熱電偶丈量端和參考端之間必需有溫差。將兩種不同資料的導體或半導體A和B焊接起來，構(gòu)成一個閉合回路。當導體A和B的兩個執(zhí)著點1和2之間存在溫差時，兩者之間便產(chǎn)生電動勢,因此在回路中構(gòu)成一個大小的電流,這種現(xiàn)象稱為熱電效應(yīng)。熱電偶就是應(yīng)用這一效應(yīng)來工作的。陜西碳化硅熱電偶保護管公司奧翔硅碳公司可靠的質(zhì)量保證體系和經(jīng)營管理體系，使產(chǎn)品質(zhì)量日趨穩(wěn)定。</p><div

src="http://tyunfile.71360.com/UpLoadFile/2019/7/27/16/636998420287924804_zbwuzi_4882160.JPG"></div><p style="text-indent:25px">選擇熱電偶要根據(jù)使用溫度范圍、所需精度、使用氣氛、測定對象的性能、響應(yīng)時間和經(jīng)濟效益等綜合考慮。 1、測量精度和溫度測量范圍的選擇使用溫度在1300~1800℃，要求精度又比較高時，一般選用B型熱電偶；要求精度不高，氣氛又允許可用鎢錸熱電偶，高于1800℃一般選用鎢錸熱電偶；使用溫度在1000~1300℃要求精度又比較高可用S型熱電偶和N型熱電偶；在1000℃以下一般用K型熱電偶和N型熱電偶，低于400℃一般用E型熱電偶；250℃下以及負溫測量一般用T型電偶，在低溫時T型熱電偶穩(wěn)定而且精度高。 2、使用氣氛的選擇 S型、B型、K型熱電偶適合于強的氧化和弱的還原氣氛中使用，J型和T型熱電偶適合于弱氧化和還原氣氛，若使用氣密性比較好的保護管，對氣氛的要求就不太嚴格。 3、耐久性及熱響應(yīng)性的選擇線徑大的熱電偶耐久性好，但響應(yīng)較慢一些，對于熱容量大的熱電偶，響應(yīng)就慢，測量梯度大的溫度時，在溫度控制的情況下，控溫就差。要求響應(yīng)時間快又要求有一定的耐久性，選擇鎧裝偶比較合適。 4、測量對象的性質(zhì)和狀態(tài)對熱電偶的選擇運動物體、振動物體、高壓容器的測溫要求機械強度高，有化學污染的氣氛要求有保護管，有電氣干擾的情況下要求絕緣比較高。</p><p style="text-indent:25px">熱電偶的基本誤差:誤差是熱電偶本身固有的，還包括上一極標準的傳遞誤差。解決方法：可采用檢定校驗的方法使其控制在允許偏差范圍內(nèi)，也可在實際測溫中將熱電偶偏差進行修正，得到的真實的溫度。絕緣不良引起的誤差：熱電偶使用時兩熱電極間以及它們和大地之間應(yīng)有良好的絕緣，不然將會有熱電勢損耗，直接影響測量結(jié)果的準確性，嚴重時會影響儀表的正常運行。解決方法：把熱電偶的引線接在鐵管內(nèi)，并將鐵管接地。把熱電偶懸空，熱電偶不與爐壁的耐火磚接觸。把參考端接地，在熱電偶(或補償導線)輸出端的一端，通過一個容量足夠大的電容接地。用屏蔽的方法，可使泄漏的電流經(jīng)過金屬屏蔽物直接接地，不在流入測量回路，從而消除干擾誤差。奧翔硅碳始終以適應(yīng)和促進工業(yè)發(fā)展為宗旨。</p><div

style="text-indent:25px">熱電偶材料不均勻性引起的誤差：此誤差和材料不均勻程度有關(guān)溫度變化越大，使熱電極各點溫度的差值越大，則材料不均勻性的影響也就越大。解決方法：可用退火的方法把它減弱，但無法完全消除。測量儀表的誤差：該誤差的大小是由儀表的精度等級決定的。解決方法：應(yīng)定期檢定效準，保證儀表的精確度等級。動態(tài)誤差：溫度變化后，測溫儀表來不及立即指出變化了的溫度，因而引起讀數(shù)誤差。熱電偶時間常數(shù)的大小是決定動態(tài)誤差大小的主要因素。解決方法：對于快送變化的溫度，由于測溫元件的熱憜性，動態(tài)誤差可能很大，必須采用小慣熱電偶或選取采樣數(shù)率較高的儀表解決。采用導熱性能好的材料做保護管，管壁要薄，內(nèi)徑要小。減小保護管與熱電偶測量端之間的空氣間隙。增加測量端介質(zhì)的流速，加快對流傳熱。奧翔硅碳產(chǎn)品適用范圍廣，產(chǎn)品規(guī)格齊全，歡迎咨詢。陜西碳化硅熱電偶保護管公司</p><p
